Yes, a good purifier will relieve your allergy symptoms.
HEPA filters are the best for catching allergens and dust, and the best manufacturer of HEPA purifiers is certainly Honeywell (http://air-cleaner-systems.com/HEPA-air-purifiers.html).
The best air purifier on the market is the Sun Pure SP-20C (same unit as the Continental Fan CX1000 air purifier) at http://www.allergy-relief-air-purifier.com/portable-air-purifiers.html This is the same unit used in hospitals and labs for its efficiency and effectiveness. Here is a video of one being used in an invitro fertilization lab where gases, dust and bacteria must be under strict control in order to preserve the embryos http://www.youtube.com/watch?v=sDDX_XWAcRY As you may be shopping around, you will find that the only air purifier that comes close to the Sun Pure SP-20C is the IQ Air GC and that is compared here http://www.allergy-relief-air-purifier.com/best-home-air-purifier.html You will notice that the Sun Pure SP-20C is much more affordable in the long run and will be the last air purifier you will need to purchase since it comes with a lifetime warranty. Made in the USA. I hope this helps.
